Adjustable base rubber for bullpup rifles

ABSTRACT

The invention relates to a part called base rubber ( 1 ) and/or butt rear rubber which is developed to be used in butts of the bullpup rifles. Said base rubber ( 1 ) has a feature that is adjustable in different sizes according to the demand of the user.

TECHNICAL FIELD

The invention relates to a part called base rubber and/or butt rear rubber which is developed to be used in butts of the bullpup rifles. Said base rubber has a feature that is adjustable in different sizes according to the demand of the user.

PRIOR ART

The bullpup rifles are typically a type of rifle in which the feeding and firing mechanism is placed behind the trigger and the grip, in this manner, the length of the barrel remains fixed and they are the rifles which are designed in order to reduce the overall length and weight of the rifle. Bullpup rifles are short and lightweight rifles based on their designs. Thus, it allows movement ability for the users with limited space. Furthermore, it offers solution to the users who is required to use smaller and lighter rifles than the other rifles.

Also, although that they are short and light weight make the bullpup rifles preferential from other rifles, the shortness of the butt causes the bullpup rifle to lose its function in normal areas of use and/or in times when the user requires a long butt.

Since the bullpup rifles have smaller sizes and light weight, it allows the user to use the same farther from his/her shoulder, on the other hand the user may have difficulty to control the bullpup rifle in conditions such as tiredness and distraction. However, in this case, the user does not have the butt length to lean the butt on his/her shoulder. In this case, there will be security problems regarding with the use of the bullpup rifle.

AIM OF THE INVENTION

In order to solve the problems of the prior art, adjustable rubber base in bullpup rifles is developed. Adjustable feature is gained to the base rubber engaged to the butt of the bullpup rifle. The user can gain distance by easily drawing said base rubber from the butt when he/she desires and obtains a long butt. The user can easily bring the bullpup rifle to its original size by easily pushing the base rubber that he/she has opened by means of pulling the same.

The user obtains butt length with different sizes by means of gradually pushing and pulling the base rubber with adjustable feature. Again, the adjustment of the base rubber is performed in a gradual manner as in the complete opening and complete closing process by means of a lock button located on the butt.

By adjusting the base rubber on the butt in bullpup rifles;

-   -   The total standard length of the bullpup rifle can be changed by         the user,     -   The size of the butt of the bullpup rifle in standard form can         also be changed by the user,     -   The bullpup rifle which provides the user with the option of         using the same only in narrow area can be used out of the         mentioned narrow areas,     -   The safety problems based on the user tiredness are eliminated.

SUMMARY

In accordance with an aspect of these disclosures, there is provided an adjustable base including: at least one base rubber which may have at least one pin, wherein the pin may enter and exit a pin housing and the pin housing may be located on a butt end of a gun stock.

The adjustable base rubber may also have the butt with at least on lock housing, which in its turn may have at least one lock, and that lock may be engaged with the lock housing and may have at least one pin hole on the lock. A one spring may be wrapped around the lock and the pin may have at least one node.

The pin housing of adjustable base rubber may be located on the butt and may pass through the lock housing.

At least one pin may pass through the pin hole and the lock may have at least one notch where the spring may rest and/or sits on.

An adjustable base rubber (1) for the inventive bullpup rifles, there is a view of the same in FIG. 1 in which it is engaged to the butt (10) and it is one of the main elements of the invention.

There are two pins (2) on the surface where the base rubber (1) and the butt (10) are connected. Said each pin (2) is engaged with the base rubber (1) with a right angle. The base rubber (1) gains movement feature with the pin (2).

Another main element of the invention is pin (2), its details can be seen in FIG. 3. There is a node (6) on the pin (2) with cylindrical form which is engaged with the base rubber (1) with a right angle. There are five nodes (6) on the pin (2) included in the Figures. However, the number of nodes (6) can be increased and/or decreased during production.

Another main element of the invention is the pin housing (9), it can be seen in FIG. 4. Said pin housing (9) is located on the surface where the butt (10) is combined with the base rubber (1). The pin housing (9) is in circular form and its diameter is as big as such that the pin (2) can pass and/or as small as holding said pin (2). Moreover, the depth of the pin housing (9) increases according to the length of the pin (2).

Another main element of the invention is the lock housing (8), it can be seen in FIG. 4. The lock housing (8) is opened from the side portion of said butt (10) such that it can pass through both pin housings (9) opened on the butt (10) with a right angle. In other words, both pin housings (9) opened on the butt (10) pass through the lock housing (8) opened on the side portion of the butt (10) with a right angle.

Another main element of the invention is the lock (3), it can be seen in FIG. 5. As well as the lock (3) is in cylindrical form, there is a pin hole (4) thereon through which each pin (2) can pass. The diameter of each pin hole (4) is as big as such that the pin (2) can pass and/or as small as holding said pin (2). Also, there is a notch (5) on the lock (3). The spring (7) which is passed through one end of the lock (3) sits on the notch (5) and/or rests on the same. Therefore, the structure of the spring (7) is in the form to wrap the lock (3) and to rest on the notch (5) and/or sit on the same.

When we consider the engagement and/or functional relationship of the abovementioned parts with each other; the spring (7) is passed through one end of the lock (3) and/or said lock (3) is passed through said spring (7), thus said spring (7) leans on the notch (5) and/or sits on the same. Then the lock (3) on which the spring (7) is located is seated within the lock housing (8) opened on the butt (10) seen in FIG. 2. When the lock (3) is seated in the lock housing (8), each pin hole (4) which is opened on said lock (3) sits such that they face the pin housing (9), however, the spring (7) prevents the complete alignment of said pin housings (9) and the pin holes (4). However, when a pressure is applied to the portion of the lock (3) outside the butt by the user, the spring (7) is compressed and each pin hole (4) forms a tunnel by aligning with a pin housing (9). The tunnel structure is disrupted and becomes zigzag after the pin holes (4) and the pin housings (9) separate from each other when the pressure applied by the user is ended.

In order to engage the baser rubber (1) with the butt (10), each pin (2) located on said base rubber (1) is fitted in the pin housing (9) corresponding the same and on the other hand, pressure is applied to the lock (3) and pin holes (4) are enabled to be aligned with said pin housings (9). Therefore, a tunnel through which the pin (2) will pass is formed by means of fully aligning the pin holes (4) and pin housing (9). Afterwards, when the base rubber (1) is engaged with the butt (10) with a desired distance and/or adjustment, the pressure applied to the lock (3) is terminated. The spring (7) pushes said lock (3) and disrupts the alignment of each pin hole (4) when the pressure applied to the lock (3) is stopped. Accordingly, each pin hole (4) leans on the node (6) that is located on the pin (2) and/or it retains said pin (2) from said node (6).

The use can rest the base rubber (1) completely on the butt (10) but also he/she can be able to make the required adjustment by pulling and/or pushing said base rubber (1) by means of pressing the lock (3), then he/she locks said base rubber (1) to said butt (10) by means of terminating the pressure applied on said lock (3).
